Value Collection 261361PR Pull Out Dowel Pin 0.5x4 in Grade 8

Product Description

The VALUE COLLECTION 261361PR is a standard pull out dowel pin used for precision alignment and locating of machine components. Manufactured from Grade 8 alloy steel, this pin measures 0.5 inches in diameter and 4 inches in overall length with a diameter tolerance of 0.0002 inches, making it suitable for close-tolerance applications where accurate positioning is critical. One end is rounded and the other end is threaded to allow extraction without a press. It conforms to ASME B18.8.2 standards. Machinists, tool and die makers, and maintenance technicians are the primary installers of this type of fastener.

This pull out dowel pin is used in jigs, fixtures, tooling plates, and machine assemblies where repeatable part location is required. The threaded pull out end simplifies removal from blind holes, reducing disassembly time during maintenance or retooling. It is appropriate for general industrial and manufacturing environments where Grade 8 alloy steel strength and tight dimensional control are specified.

Key Features

• Threaded end allows extraction from blind holes without a press or punch
• Rounded opposite end for guided installation into bored holes
• Grade 8 alloy steel construction for high strength and wear resistance
• Diameter tolerance of 0.0002 inches for close-tolerance locating applications
• Conforms to ASME B18.8.2 dimensional standard

Compatibility

Designed as a standard OEM-style replacement or new-installation pull out dowel pin for jigs, fixtures, tooling plates, and precision machine assemblies requiring a 0.5-inch diameter locating pin per ASME B18.8.2.

Installation Notes

Pull out dowel pins are typically installed by machinists or maintenance technicians using a press or mallet into precision-reamed holes. Ensure the receiving hole is properly cleaned and deburred before installation. Use the threaded end with an appropriate extraction tool or threaded rod to remove the pin without damaging the host material. Consult applicable machinery safety lockout procedures before servicing any assembly containing these pins.
